my games are being ruined by constant crashing

my internet connection speed is sub par and that is something I have come to play around since starting league, but a patch or 2 ago I started experiencing random spikes in ping and instead of automatically trying to reconnect, it totally crashes, kicks me out of the game and a pop up for bugsplat appears. I looked at older posts regarding bugsplat and made sure my drivers were up to date and such but It happens so often during games now I am becoming irrelevant, walking into lane and having to manually reconnect to a game. I have still been able to pull off wins but only because my team snowballs without me. this is starting to cause verbal harassment from team members that think I am just trolling. this has been happening since the new summoner's rift beta came out for bot games and team builder and has still not been fixed. this sort of thing breaks games and causes infighting ruining the games experience. I would hate to be constantly reported for afk for something else I cant control.
